如何从对象到局部变量C＃获取值

Question

i have following code please help me how to get values from object

 APIKarho objapi = new APIKarho();
           object obje = objapi.GetBookingFromAPI();

           string ss = obje.booking_id;

Answer 1

You should cast the object to the class it originally is (what class is the object returned by GetBookingFromAPI() ) before you could access its field/property/method . Example:

public MyClass { // suppose this is the original class of the object returned by GetBookingFromAPI
    public int booking_id; 
}

APIKarho objapi = new APIKarho();
object obje = objapi.GetBookingFromAPI();
string ss = ((MyClass)obje).booking_id; //note the casting to MyClass here

Answer 2

You need to find out what type GetBookingFromAPI() returns, and change the type of obje. Just move your mouse over GetBookingFromAPI().

GetBookingFromAPIType obje = objapi.GetBookingFromAPI();

string ss = obje.booking_id;

Answer 3

If your api returns an object of an unknown type or a type that you cannot cast to you could use the dynamic keyword.

dynamic obj = api.GetBookingFromAPI();
string ss = obj.booking_id;

Note that this works only if booking_id is actually a string.
